LAKE MEAD is easily identified by its three-pronged shape.  It is located on/in? the Colorado River in the states of Nevada & Arizona. Founded by water impounded by the Hoover Dam, it is the largest reservoir in the U.S.

Before Hoover Dam was built the Colorado River was a much different river than we see today. In place of the warm, silt-laden stream we see today, in pre-dam days there lay cool, clear river.

Gravity of density (turbidity) is defined as currents in which the flow takes place due to relatively small units of in-unit weight between two fluids. The term turbidity current is generally only applied to flows of sediment suspended in water.

These sediments form a continuous cover along the entire extent of the original Colorado River valley from the eastern extremity of the lake to the Hoover Dam in the west. Sediment filling the original Colorado River valley is thickest to the east at the mouth of the Colorado River.

Eventually, enough of this sediment may come down the river to fill up the whole lake, however it's not expected to happen for hundreds of year.
